AFAICT from a quick look at the code, you won't get any meaningful parallelism unless you have several large DBs and/or several large tablespaces. It looks like the assumption was that issuing link() requests in parallel wouldn't help much but just swamp your disk if they're all on the same filesystem. Maybe that could use rethinking, not sure. regards, tom lane
